Iron Maiden has recorded three songs that share the same title as Bruce Dickinson’s solo songs: “The Wicker Man”, “The Alchemist”, and “The Man of Sorrows”.
In 8 years, no one has mentioned two hits from 1980: 9 to 5 by Sheena Easton and 9 to 5 by Dolly Parton. (The former was a British song renamed as “Morning Train” in the US to avoid the confusion.)
In the U.S it was credited as Morning Train(9 to 5), though elsewhere it was Morning. Train. I wanted to mention it but was hesitant and you beat me to it. By the way they were both #1 singles in Spring 1981. In Canada the Easton song was known only as Morning Train.
